Combined treatment with etanercept 50 mg once weekly and narrow-band ultraviolet B phototherapy in chronic plaque psoriasis.

The combination of etanercept, a tumour necrosis factor α inhibitor, with narrow-band ultraviolet B (NB-UVB) phototherapy has recently been reported to be effective in moderate-to-severe plaque psoriasis, yielding better results than either monotherapy. To assess the efficacy and safety of this combined treatment using the lower approved etanercept dosage. In this single-arm open-label study patients received etanercept 50 mg once weekly combined with NB-UVB phototherapy three times weekly for 8 weeks, followed by etanercept alone until week 12.

Giant verrucous porokeratosis of Mibelli mimicking psoriasis in a patient with psoriasis.

Histologically the lesion combined features of porokeratosis at the periphery and of psoriasis at its center, a picture recently described as "psoriasis encircled by porokeratosis.
